Amendment 3.7.5 The name of the invention is amended as follows. Title of the invention Anti-theft device The scope of the utility model registration claim and the brief description of the drawings are amended as follows.

[Scope of Utility Model Registration Request] 1. With the anti-theft device, the vehicle owner must move away from the driver's seat and remove the key when getting out of the vehicle. The starter motor circuit is cut off and switched to the contactor under the driver's seat, where the current remains. 2. When a thief entered this car from the outside and sat down in the driver's seat, the contact point of the contact device was activated.
The current will be interrupted by the engine circuit depending on the operation of a relay mounted next to the engine. Even if the key is connected directly, the engine will not start. 3 When I sat down in the car with the key removed, the alarm continued to ring. Once this relay operates, the circuit cannot be easily passed on to a third party, so it is highly effective in preventing theft of a vehicle, and the device configuration is extremely simple.
A theft car prevention device that can be manufactured at low cost.

[Brief Description of the Drawings] The drawings show the implementation of the present invention. Figure 1 is a block diagram and current system wiring diagram showing the main parts of the invention, Figure 2 is a schematic diagram of the key and switch structure, Figure 3 is a diagram of the contactor installed under the driver's seat, Figure 4 is a structural diagram of the engine circuit disconnection relay and the starter motor circuit is connected, and Figure 5 is the above-mentioned
The relay shown in the figure is a structural diagram with the starter motor circuit disconnected depending on the operation, Figure 6 is a structural diagram of the relay improved from Figure 4 above, with the circuit connected, and Figure 7 is a structural diagram with the starter motor circuit disconnected. 8 is a diagram of the contactor under the driver's seat board, FIG. 9 is a sectional view of the contactor, and FIG. 10 is an enlarged structural diagram of the above-mentioned FIG. 4.

Claims (1)

[Claims for Utility Model Registration] 1. An engine circuit disconnection relay related to preventing theft of a vehicle. 1. Power source 12V. 2. Key. 3. Circuit disconnection relay. The current is always stagnant in the contactor under the driver's seat at 6. 2. When a thief enters the car from the outside and sits down in the driver's seat, current is transmitted to the cut-off relay in 3, which cuts off the starter motor circuit in 4, so the engine does not start. 3 Once the cut-off relay operates, the starter motor circuit will not connect unless you intervene. 4 Once a circuit is cut, it cannot be easily passed on to a third party, and even if it is, it will take a long time. 5 The alarm continues to sound while the intruder is sitting in the driver's seat. The alarm circuit is connected to the secondary side of contactor 6 (under the driver's seat). 6 Install the cutter next to the starter motor. Additionally, car owners leave their seats when removing the key. 7 This device does not require a sensor, but some key parts will be improved. The contacts under the driver's seat are simple. Circuit-disconnecting relays shall consist of permanent magnets and shall be made as compact as possible. 8. Although the device configuration is simple, even if an intruder makes a direct connection at the key, once the starter motor circuit is disconnected, it will not be connected again. The present invention provides a theft vehicle prevention device that is simple and effective in preventing theft.
